He founded the International Free Press Agency (AIPL, l' Agence Internationale de Presse libre), where he published most of his work on these themes, achieving some prominence with an interview on esotericist and ufologist Richard Glenn's TV show Ésotérisme Expérimental, in which he repeatedly warned his audience about the dangers of a World Government.[2]

In 1995, he published his most detailed work, Les Protocoles de Toronto (6.6.6), modeled upon The Protocols of the Elders of Zion, wherein he said a Masonic group called "6.6.6" had, for twenty years, been gathering the world's powerful to establish the New World Order and control the minds of individuals.

By 1995 and 1996, Monast said he was being hunted by the police and authorities for involvement in "networks of prohibited information." He had homeschooled his two children, who were then taken away and made wards of the state in September 1996 so that they would receive a public education. He died of a heart attack in his home in December 1996, at age 51, the day after being arrested and spending a night in jail.[5] His followers claim his death was suspicious, suggesting he was assassinated by "psychotronic weapons"[2] to keep from continuing his investigations,[6] and that the Mel Gibson character in the 1997 film Conspiracy Theory was modeled on him.[2]

Copies of his works still circulate on the Internet, and have influenced such later conspiracy theorists as American evangelical preacher Texe Marrs.[1] Some of his later works have been reissued by French publisher and conspiracy theorist Jacques Delacroix, along with others writing on the themes of Monast's conspiracy-related work.[7]
